Worked Example — Mars Step-by-Step

This page walks through the complete Planet Capacity calculation for Mars using the sample chart (3001-02 M, 14-Mar-1987 09:48 AM, Pulivendula, AP — Aries Ascendant). Every formula, lookup, and intermediate value is shown so you can follow the logic end to end.

Mars at a Glance

Before we begin the calculation, here is a summary of Mars's chart placement and the key properties we will need throughout the steps.

Key chart data used in this example:

• House occupancy: H1: Mars  |  H5: Moon  |  H6: Ketu  |  H10: Saturn + Venus  |  H11: Mercury + Sun  |  H12: Jupiter + Rahu
• Venus is in Bhava 10, House 10. Venus lords H2 + H7. Venus is a Functional Malefic (FM) for Aries ascendant.
• Aries lordships: Su: H5  |  Mo: H4  |  Ma: H1 + H8  |  Me: H3 + H6  |  Ju: H9 + H12  |  Ve: H2 + H7  |  Sa: H10 + H11

Step 1 — Light Score

Light represents a planet's operational brightness, determined by the RC 7-Rule System (retrograde analysis). Each of the three entities (Planet, Star Lord, Powerful Planet) carries a Light value that modifies its entity score.

Mars's Default Light

Mars is direct in the natal chart (not retrograde at birth on 14-Mar-1987). After evaluating rules R1 through R7 of the retrograde system, a direct planet with no retrograde disruption receives a Default Light of 100.

Which Light applies to each entity?

The rule for Light assignment is:

• Planet entity → uses the original planet's Default Light (Mars's Light).
• Star Lord entity → uses the original planet's Default Light (Mars's Light).
• Powerful Planet entity → if PW is the same planet as SL, use the original planet's Default Light. If PW ≠ SL, use PW's own Powerful Light (R5 skipped).

In this chart, PW = Venus and SL = Venus — they are the same planet. Therefore PW also uses Mars's Default Light.

Step 2 — Performance: Planet Entity (20%)

The Planet entity represents Mars itself. Its entity score combines a Position Score (70% weight) and a Lordship Association score (30% weight).

Position Score

Mars sits at Bhava 12, House 1. Since Bhava ≠ House, we apply the 75/25 split using Mars's Aries position table.

Looking up Mars's scores in the Aries position table:

Lordship Association (Planet Entity)

The Planet entity is not penalized for its own lordship. It is only penalized for dusthana lordships brought in by conjunction and aspect.

• Mars is in House 1. Which planets conjunct Mars in H1? None — Mars is alone in H1.
• Check special aspects reaching H1: Saturn (H10) casts its 7th aspect to H4, 3rd aspect to H12, 10th aspect to H7 — none hit H1. Jupiter (H12) casts its 7th aspect to H6, 5th aspect to H4, 9th aspect to H8 — none hit H1. No other planet has special aspects that reach H1.
• Result: no conjunction or aspect penalties apply.

Planet Entity Score

Apply Light:

Step 3 — Performance: Star Lord Entity (50%)

Star Lord = Venus. The SL entity is the most influential component, carrying 50% of Performance.

Position Score

Important: We always use the original planet's position table, not Venus's own table. So we look up Venus's Bhava/House position in Mars's Aries table.

Venus is at Bhava 10, House 10 — Bhava = House, so no 75/25 split is needed. We use the full score.

Lordship Association (SL Entity)

The SL entity is penalized for the SL's own lordship plus any conjunction penalties from planets conjunct the SL.

• Venus's own lordship: Venus lords H2 and H7. The dusthana list is H3, H6, H8, H12. Neither H2 nor H7 is a dusthana → no own penalty.
• Venus's conjunction: Venus is in H10 with Saturn. Saturn lords H10 and H11. Neither is a dusthana → no conjunction penalty.

SL Entity Score

Apply Light (Mars's Default Light = 100):

---

Step 4 — Performance: Powerful Planet Entity (30%)

Powerful Planet = Venus (same as Star Lord).

Position Score

Same lookup as the SL entity — Venus at B10/H10, using Mars's Aries table.

Lordship Association (PW Entity)

The PW entity is penalized for the PW's own lordship plus any conjunction penalties — the same analysis as SL above.

• Venus's own lordship: H2 + H7 — no dusthana → no penalty.
• Venus's conjunction: Saturn in H10, lords H10 + H11 — no dusthana → no penalty.

PW Entity Score

PW Light

Since PW (Venus) is the same planet as SL (Venus), the rule dictates that PW uses the original planet's Default Light = 100.

---

Step 5 — Total Performance

Performance combines the three entity scores with their respective weights.

---

Step 6 — Resource Score

Resource measures a planet's intrinsic dignity — its raw material regardless of where it sits in the chart. It is composed of Base + Boosters − Negatives, clamped to 0–100.

Base

Mars is in Aries — its own sign. Mars is also within the Mooltrikona range (0°–12° Aries), so the highest base condition applies.

Boosters

Negatives

No negatives apply. Mars is not in Gandantara, not combust, not a war loser, and has no bad associations.

Final Resource

Step 7 — Final Capacity

Capacity combines Performance (70%) and Resource (30%) into a single score.

---

Step 8 — Invert Check

The Invert rule applies only to Functional Malefics. A high score for an FM planet means it is very effective at causing harm, so the score is inverted (100 − score) to reflect that a "strong malefic" is actually bad for the native.

Mars is a Functional Benefic for Aries ascendant. Therefore Invert does NOT apply.

Rating: Excellent — Mars is an extremely capable planet in this chart. As the Lagna lord in its own sign with Mooltrikona dignity, and with Venus (SL and PW) well-placed in H10 with no dusthana lordship penalties, Mars achieves a near-perfect score.
